Morphology

photochromic + eyewear

The adjective 'photochromic' (changing color with light) directly modifies 'eyewear' (items worn on the eyes), so the compound simply means eyewear that changes/darkens in sunlight and clears indoors. This is a straightforward adjective + noun composition whose meaning is compositionally predictable for a learner who knows both constituent words.

Etymology

Photochromic eyewear comes from its parts, with photochromic meaning lenses that 'change color' with light and eyewear meaning glasses. So these are glasses whose lenses go 'dark' in sunlight and 'clear' indoors.
